1. How easy/difficult was it to pull off this movement? Why? What helped you to finally get the

2. Rotational Inertia is defined as a measure of an object’s resistance to being turned, depending on
both the mass of the object and the distribution of the mass. Thinking about the distribution of
your mass when you did the movement, what positioning of your body worked best?

3. Angular momentum is the measure of the extent to which an object will continue to rotate about
that point unless acted upon by an external torque (which was not present in this case). Since you
did not continue to rotate, your angular momentum was 0. But, you were still moving. Can you
explain why this angular momentum was still zero and the conservation of angular momentum

4. Explain how Newton’s Laws pertain to the physics of skateboarding. Use examples or pictures as
well as words.
Newton’s First Law: An object at rest or moving at a constant speed continues to do so until a net force
acts on it.

Newton’s Second Law: An object acted upon by a net force will accelerate in the direction of this force.

Newton’s Third Law: Forces always act in equal but opposite pairs.
